Thank you for your post.
At this time, FileMaker Go does not have any syncing options.
Instead of having each person run a separate copy of the database, have you tried connecting to the host file via 3g? This would allow users to have all the information available real-time and all changes would be recorded immediately and all devices would have the information available to them immediately.
If you still need syncing capability, I suggest you enter this request into our Feature Requests web form at:
The suggestions entered into this web form are read by our Development and Product Management departments where they discuss and consider these suggestions for inclusion in a future release.
Although I could easily copy your post and paste it into the web form, there are additional questions asked that only you can answer.
